Warning From Topper Shutt: Ocean Temp Is Cooler Than On Thanksgiving

Some of the best boating news over the Memorial Day weekend (Thank you, veterans) has been penned by DC area weathermen dutifully repeating warnings issued by the National Weather Service. WUSA-TV 9 meteorologist Topper Shutt is the latest contributor with his piece in the Sunday, May 29, 2011 edition of The Washington Examiner.

Shutt's "Chilly water" message warning of hypothermia appears in the Weather News You Can Use column. Sadly, WashingtonExaminer.com did not post an active link to the story, so as a public service, I'm posting the entire piece here. This will assure two or three more people, mostly relatives, get this information.

"Many people flock to the shore for Memorial Day weekend. If I suggested you go to the beach on Thanksgiving, you would think I was crazy. However, the ocean is actually warmer on Thanksgiving Day than on Memorial Day.

"The water temperature on Thanksgiving Day is typically 64 degrees. On Memorial Day, it's only about 61 degrees.

"The ocean is still recovering from winter and hasn't received the added boost from the Gulf Stream. The atmosphere is vertically mixed, but the ocean is horizontally mixed.

"If you get into the water this weekend, don't stay in long. It is possible to get hypothermia in water that is about 50 to 60 degrees. Hypothermia can set in between one and two hours.

"Although the sun might not feel that hot, late May sun is equivalent to July sun, so remember to apply sunscreen."

Be Careful On The Potomac

ANNAPOLIS, Md. — Maryland Natural Resources Police say they plan to patrol aggressively on waterways across the state this holiday weekend.

Natural Resources Police say officers will target boaters driving in a reckless or negligent manner or under the influence of alcohol. And they will also be making sure boaters have required safety equipment.

Authorities also are advising boaters to keep a cautious eye on the upper Potomac River, where recent rains had pushed the river to hazardous levels. NRP says an advisory for the upper Potomac has expired, but any significant additional rainfall could cause hazardous conditions again.

NRP says last year its officers responded to more than 323 boating accidents that led to 13 deaths.

Montgomery County Fire and EMS crews will be handing out hundreds of these fliers in Great Falls Park reminding people that you cannot swim, wade, or drink alcohol there.

Because as enticing as the Potomac is this time of year, it is always dangerous. Crews pulled a 12 year old boy who was swimming near White's Ferry after he became fatigued and couldn't make it on his own.

Mark Gleason, who patrols the C & O Canal on bicycle for the US Park Service, says the Potomac is very deceptive.

In some places, the power of the Potomac is obvious. But in others--a deadly hazard lurks beneath the tranquil surface.

"Most of the accidents people here are when they step in and the water is much faster underneath and it sweeps them away."

All this talk about the swollen waters of the Potomac is a reminder that it's the best time to see the river's Great Falls, the most awesome natural sight in the DC Metro area. The Falls' Maryland shore offers more access points for an up-close, intimate view of the river and the C & O Canal. The view from the Virginia shore is simply spectacular.

The Maryland side is accessible through the Chesapeake & Ohio Canal National Historic Park. Access to the Virginia side is through Great Falls Park. Both are National Park Service facilities.

Don't Go Into The Water

All the news focuses attention to the Mississippi River flood and the unfortunate circumstance of the people there. We have our own problems with the waters around D.C.

Flooding Potomac presents hazards for area boaters according to an online story by WTOP.

Heavy rains in the area has the Potomac River cresting its banks and creating navigational hazards for all boaters. The D.C. Harbor Police advises all boaters to stay off the Potomac through the weekend (20-22 May 2011).

A similar story on www.nbcwashington.com says the worst of the flooding is probably over, but advises boaters to stay off the Potomac this weekend. That story gave high tide (11:15 AM and 11:56 PM at Key Bridge) on Friday, 20 May, as a time for special caution for boaters and anyone along the waterfront.

The National Weather Service issued a Flood Warning for the Potomac River at Point Of Rocks affecting Frederick (MD) and Loudoun (VA) Counties and at Little Falls affecting Montgomery (MD) and Fairfax (VA) Counties. The warning is in effect until this evening. The warning was issued at 4:24 PM today.

A warning means that flooding is actually occurring. Take extreme caution when driving through flood areas. A vehicle can be swept away in as little as two feet of flowing water. Cars are not boats!

If you have first-hand knowledge of conditions along our waterways, leave a comment.
